✦ Synopsis

The stability of steady-state cocurrent and countercurrent gas-liquid annular flow is considered. Transient formulation, based on the two-fluid model, results in a Kelvin-Helmholtz type ofinstability. Thus, this formulation is not suited for analyzing the steady-state stability of annular flow, since steady-state annular flow is inherently unstable with respect to the interfacial structure. Various ways of transient formulations which neglect the Kelvin-Heltiholtz contribution to instability are proposed, resulting in a simple and useful criterion for the stability of steady-state annular flow.
